ユーザーから、個人所有の新しいタブレットが会社の Wi-Fi ネットワークに接続できないという報告がありました。ユーザーは他のデバイスで Wi-Fi ネットワークに接続でき、タブレットは最新のソフトウェアを実行しています。この問題の原因として最も可能性が高いのは次のどれですか。
正解:B
When a user reports that a new, personally owned tablet will not connect to the corporate Wi-Fi network, but other devices can connect, and the tablet is running the latest software, the most likely cause of the issue is a blocked MAC address. Here's why:
MAC Filtering: Many corporate networks implement MAC address filtering as a security measure. This involves only allowing devices with specific MAC addresses to connect to the network. If the MAC address of the new tablet is not on the allowed list, it will be blocked from connecting.
Check Network Settings: To troubleshoot this, the network administrator can check the network's MAC filtering settings to see if the tablet's MAC address is blocked.
Add MAC Address: If the MAC address is blocked, adding the tablet's MAC address to the allowed list will resolve the issue.
Other options like incorrect encryption settings or outdated drivers are less likely because the user can connect with other devices and the tablet is running the latest software. Disabled location services do not affect Wi-Fi connectivity.
